DIRIGIBLE HEADLIGHT.

Application led January 26, 1922. Serial No. 531,964.

T 0 all w homy t may concern.:

Be it known that I, FRANK OrnnnBA, a citizen of the United States of America, residing at Burgettstown, in the. county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Dirigible Headlights, of which the following is a specification.

This invention relates to certain new and useful improvements in dirigible headlights for automobiles, and has particular reference to the idea of operatively connecting the headlights to the steering mechanism of the automobile so that when the front steering wheels of the automobile are turned to either the right or left, the headlights will be similarly shifted to cast the rays therefrom in a direction directly forwardly of the travel of the automobile.

In certain automobiles, such as the Ford, a stud screw projects forwardly of each steering knuckle at the front end of the automobile, the present invention being especially designed for adjustable connection with said stud bolt to permit easy and quick mounting of the device upon an automobile of this type.

With the above general objects in view and others that will appear as the nature ol the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown `in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 shows by dotted lines a front elevational view of an automobile with the present type of dirigible head-light operatively mounted thereon,

Figure 2 is a horizontal sectional view taken on line II-II of Fig. 1, showing the dirigible headlight, frame structure operatively connected to steering knuckles of the automobile,

Figure 3 is a fragmentary detail sectional view showing the perpendicular shaft supw porting a headlight disposed rearwardly of the forward cross bar of the frame chassis,

Figure 4 is a detail sectional view, similar to Fig. 3, showing the perpendicular shaft disposed forwardly of the chassis frame bar, an

Figure 5 is a fragmentary detail sectional view showing the screw studs or bolts carried by the steering knuckle of the antoniobile with the dirigible headlight mechanism adj ustably connected thereto.

lThe invention is illustrated as attached to an automobile of the Ford type, the latter embodying a chassis frame including a forward cross bar 1 carrying brackets 2 at the ends thereof for supporting steering knuckles 3 associated with wheels l.. In certain types of automobiles, such as the Ford automobile, a screw stud or bolt 5 is carried by each steering knuckle and projects forwardly thereof, the dirigible headlight mechanism disclosed in this application being operatively associated with the screwstuds 5.

YThe support for the headlight mechanism includes a bracket of substantially Ll-shaped formation having side arms 6 and a cross connecting` arm i", the side arms enclosing the chassis frame bar 1 and anchored thereto by the bolts 8 extending through the free ends of the arms 6. in Figs. 3 and et, an arm 9 projects rearwardlj7 from the Ushaped bracket and has vertically ournalcd therein, a lamp support ing shaft 10, said shaft being further supported by the bracket arm 'l1 secured to and projecting laterally from the body 12 with a collar or disk 13 carried bv the shaft 10 to be supported on the bracket 11. It will therefore be seen that the shaft 10 is freely rotatable in the bracket arm 9 and also in the bracket arm 11 with the disk 13 fixed to the shaft resting on the bracket arm 11 to hold the shaft at its proper elevation. A headlight lamp 14 is adjustably connected as at 15 to the upper end of the shaft 10 and moves with the shaft.

The connection between the steering knuckles 3 and. the lamp supporting shaft 10 in cludes an internally threaded socket memn ber 16 adjustably threaded onto the screw stud. 5, shown more clearly in Figs. 2 and 5, the socket member 16 associated with each screw stud being pivotally connected as at 1'1" to the outer ends thereof, to a link arm 18, the other end ofthe link arm being pivot ally connected as at 19 to the rod or arm 20 with the other end of the arm 2O adjustably secured to the lamp supporting shaft 10 as indicated by the numeral 21.

The steering mechanism for the front wheels of the automobile includes a cross its shown more clearly steering shaft having end link 'oni'iections 2B with the steering' knuckles 3 as shown iu Fig. 2, the rod ltattached to the steering;- shaft 22 being operatively associated with the steeringpost of the automobile.

From the above detail description of the device it is belieyed that the construction. and operation thereoit will at once be apparent7 it being noted that the lamp supporting shaft l() may be either disposed rearfardly or `forwardly ot the 'front cross channel bar 1 oi the chassis trame, as shown in Figs. 3 and et while the arm 2t) ot' the mechanism for shifting the lamp support-ing post l0 is disposed upwardly ot' the chassis trame bar l. Upon shittfngmovement ot' the steering wheel 4L of the automobile in either direction, by their association with the steering knuckles 3. the connection between the stee"- ing` knuckles and the lamp supirborting post 10 provides 'for a simultaneously rotatable movement oi the lamp supportingv post to cause the lamps 14 to project the light rays in directions directly forwardly oit the automobile. As certain automobiles. as above stated are equipped with the screw studs the dirigible headlight mechanism associated with the automobile, and adapted tor attachment to said screw studs, only embodies the mounting bracket 'for the chassis frame bar, the lamp post. and the con nectinggv elements between the lamp post and the screw studs. These elements are capable ot manufacture at a low cost and installation or mounting;- thereot upon an automobile does not necessarily require the services of a skilled mechanic.

i ,astma llil'hile there is herein shown and described the preferred embodiment ot the present invention, it is nevertheless to be understood that minor changes may be .made therein without departing); from the spirit and scope thereof.

That is claimed as new is In a dirigible headlight for automobiles, substantially U-shaped bracket arms secured to the forward bar oi the chassis, substantially U-shaped bracket arms extending laterally of the body oi the automobile, the said U-shaped bracket. arms consisting lot parallel side arms and a cross connecting Vertical arm lying at right angles to the said side arm, a bolt extending;` through openings in the free ends of the said side arms for anchoringl the said bracket member to its proper place upon the vehicle, an arm Vformed integrally with the said U-shaped bracket member and extending` horizontally therefrom, lamp supporting' shafts `iournaled in the said horizontally extendingv arms of the bracket. members, disks fixed to the said shafts and rest-ing' upon the bracket arms that extend laterally ot the body ot the automobile For holding'the sha't't at its proper elevation. a screw stud carried by each steering knuckle. an internally threaded socket member adjustably mounted on each screw stud. connecting` link arms associated with the socket members and the lamp supporting' sha i't7 and lamps adjustably mounted on said shafts.

ln testimony whereotl I afx my signature.
